“The Young Assassin” Melvin Guillard (27-9-2) and Jim Miller (20-3) will enter the Octagon for a lightweight contest Friday as the UFC presents UFC on FX: Guillard vs. Miller, the company’s first offering under its newly minted contract with media giant FOX. The card has four fights slated to appear on the FX network, all of which hold interesting potential for UFC fans. “The Dentist” Josh Neer (32-10-1) and “Bang” Duane Ludwig (21-11) both have the ability to put on a stand-out showing. “HD” Pat Barry’s (5-5) heavyweight throwdown against Christian Morecraft (7-2) not only pits the brawler against the boxer but it holds additional excitement as either fighter could easily lose his job with a loss. Perhaps one of the most interesting bouts sees Mike Easton (8-0) pit his officially undefeated record against journeyman fighter Jared Papazian (13-6-1) in the latter man’s UFC debut.
